how do display nicks in respective colors

[Nasr]

do we need an add on to display users in their groups colors throughout the forums? like in the online block, last post, etc...?

In some cases, it's not doable as the data isn't exposed (last post). In other cases, it'd just need a template modification (online users).

Some areas don't use the markup, but you can edit the templates to add it. For example:
